To allwhom imag/concern:

Beit lknown that I,..IoHN ROY ARMINGTON,

acitizen of the) United States, residing at Roanoke, in the county of Roanoke and State of Virginia, have invented new vand useful Improvements in Water-Heaters, of which the .following is a specification.

This inventionrelates to;anelectri c water heater des' ned especially for use in connection wit water service or supply pipes haviv a discharge faucet, the object of the invention being to provide a heater for use in connection with a llavatory, bath or sink supply pipe arranged in the pipe adjacent the faucet and which may bev thrown into operation for furnishing waterqf any de sired temperature up 'to :the 'boiling .point for direct discharge from -the faucet.

A further object of .the invention is to provide a simple and .efficient construction of` water heater which ma.v -be arrangeddn the supply pipe below the t] p or Slab of the bowl and thrown into and out. of operation at will by the use of aswitoh 'having an operating device movable through the slab, whereby the apparatus may be rendered operative at any time for the supply of hot water.

The invention consists of the features of construction, 'combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in Which:-

Figure 1 is a sectional elevation showing the application of my invention. Fig. 2 is a front view of the switch box with the cover removed. Fig. 3 is a horizontal transverse section through the heater on the plane indicated by the line 3 3 of Fig. 1.

Referring to the drawing, 1 and 2 designate sections of a water supply pipe, between which my improved electrical heater 3 is interposed, the upper section 2 being illustrated as extending through the top or slab 4 of a lavatory' or other similar bowl or receptacle and is provided with a water discharge faucet 5.`

The heater 3 consists''f a tubular casing 6 exteriorly threaded at its upper and lower ends tp receive closure caps 7, which caps have internally threaded openings to re- .ceive the threaded ends of the pipe sections 1 and 2, by which thetube or casing is closed and coupled between the sections of the water supply pipe.

Within the cas1ng-is arranged a heating thereof, and is preferably formed of an outer section 9 .andaninner section 1Q, integral at their lower ends with each other. In practice the 'two 'sections are :preferably formed from a single tube of cop er orlike conducting material bent into the described shape, the ends -11 `and 12 0f .each tube,

which constitute the terminals of the u per ends of the coil sections, 'being extends upwardly intopthe upperlcap 7 and outwardy through -one side thereof, as hereinafter" described. Within the copper tube is a rel sistance wireg'i'between which and the wall of the'tube is arranged a'suitable body of non-combustible insutlating material 15, .the construction being such that a current sup' ply to the wire 14 will, throu h the generated resistance, produce heat y which the coil itself will be heated to a 'high tempel'-` atureand the heat-radiated therefrom within the casing 6. Y f

Y'Secured to one side of-the upper cap or coupling 7'is a switch box or casingl'v preferabl7 made of porcelain or other'suitable material and having an open front adapted to be closed'by a cover plate 17. Secured to the rear wall of this box are conducting plates 18 having a lower set of binding screws 19 to which electricalfeed wires 20 leading from any suitable source of supply are connected. The plates 18 are also provided with'binding screws 21 to which are attached fuse wires 22, which connect the same with switch contacts 23, which are adapted to be electrically connected with other switch contacts 24 by the knives of a pivoted knife switch ,25. The contacts 24; are connected with conducting plates 26 having binding screws 27 to which the terminals 28 of the resistance wire 14 are connected, so that whenthe switch is thrown the resistance wire 14 will be connected with the feed wires, as will be readily understood. The terminals28 extend from the ends 12 and 13 of the coil sections 9 and 10 through the upper cap 7 into the switch box,y as

shown.

The switch 25 is of bell crank form and is normally held retracted by a spring 29 which is also designed to give a quickbreak. lhe upper arm of this switch has a slip- ]oint connection with the lower end of a vertically movablel rod or plunge!` 30 which passes upwardly above the top of the bowl through a guide tube 31 carried by and exelement 8, which extends 4the full' length tending through the slab 4. The upper end of the rod is .threaded to receive a cap 82 which slidably engages said tube 31 and con tains a coil spring 33 bearing terminally against the tube and cap,by which the cap is normally held upwardly or retracted and the rod 30 drawn up to hold the switch 25 in open or cut off position. It will be understood that the cap 32 forms a nger piece by which the rod 30 may be depressed to throw the switch into engagement with the contacts, whereby current will be supplied to the resistance coil, heating the same to a high degree so that the water passing through the casing G to the faucet 5 will be heated.

It will be seen from the foregoing description that my invention provides a compact form of electrical heater which may be conveniently applied to the water supply pipe in juxtaposition to the faucet and thrown into operation to heat the water liowing to the faucet. lllhen the switch is open the water will feed tothe faucet in the usual -Way as will be readily understood, but by simply closing the switch the coil may be heated to heat the water passing therethrough. The degree of temperature to which the water is heated will depend, of course, on its rapidity of iow throughthe faucet and by proper control the water may be furnished at any desired temperature up to the boiling point.

Having thus described the invention what is claimed as new is l. An electric heater comprising a tubular casing, caps at the ends of the casing, a heating element within the casing including a resistance wire having its terminals extending exteriorly through one of said caps, a switch box carried by said cap and provided with contacts connected with said terminals, a switch within said box to engage said contacts, and means for operating the switch.

2. In a. water heater, the combination with a support, of a faucet mounted thereon, a water supply pipe arranged below the support and communicating with said faucet, a casing in said pipe, a heating medium within the casing including a double coil having its elements arranged one within the other and a resistance wire insulated from said coil and having its terminals extending to the exterior through the casing, a switch mounted upon the exterior of the casin to engage said terminals, means for norma ly holdin the switch retractedJ and a spring retracted switch closing device connected with the switch and extending'through said supporting member adjacent the faucet.

In testimony whereof I aix my signature in presence of two witnesses.
